Further Evaluation: After the initial telephone screening, potential subjects will meet with the principal investigator, Dr. Eda Gorbis, who will ask the subject to sign an informed consent form (ICF). The research procedures and treatment will be described in detail to the subject and any questions will be answered by the principal investigator. The ICF will be signed by the subject and the principal investigator, agreeing to those procedures in the study that are considered research, acknowledging that their participation is voluntary, and that they have been informed of the risks and benefits of the study. Research procedures include cognitive testing, standardized rating scales, and clinical assessment questionnaires discussed below.
